I will be visiting Las Vegas May 8th-12th. I was supposed to meet up with a couple of my dearest friends but due to unforeseen circumstances, they can no longer make the trip. This trip is much needed for my sanity and I am not about to cancel it. Any tips/suggestions for a single person to fully enjoy five days in Las Vegas alone?

In your April 27, 2011 QOD, you told us that there would be 80 additional taxis added for a big fight night. I searched the archives and didn't find any statistics on how many taxis are in Vegas, how many are typically on the road during peak vs. off peak times, etc. I'm curious what percent of the total taxis the 80 represent.

What's the story behind holding all the cards on a dealt 4-of-a-kind in video poker? What does it matter if you hold all five or draw one?

Any idea what happened to the power at Bally's last Saturday, 4/23? We were crossing over the strip from Bellagio and all the lights on the Bally's property were dark.

How far in advance do you get word from the Palms as to their schedule for Playmate signings? For example, they seem to usually do the weekend in the middle of each month. Any idea if they'll do that for PMOY and PMOM on May 13-14 following the PMOY announcement weekend on May 6-7? Same question for subsquent months. Would like to have a chance to plan travel to coincide if they do it on a regular schedule.

How's this for morbid curiosity? Today's News mentioned a jumper at Cosmo. All cities play their suicide numbers close to the vest for good reason, but do you have any idea what Vegas' numbers are, both total and in relation to other cities? Are many of them really tourists or is that just a popular myth? How many are hotel jumpers?

I was looking at an aerial view of Las Vegas and noticed that the Hilton had a couple of swimming pools on their roof. Are these pools exclusively for high rollers? And how many other casinos have rooftop pools or pools not for the general public?

Is Phyllis McGuire still alive and what has happened in her life since she quit singing with her sisters?

Are there any reasonable-sized casinos that still have coin-in machines? I understand it's cheaper to have TITO machines and the supposed benefits, but there's nothing like the clink of the coins and the feel of them in your hands. Yup, dirty hands, but it's just more fun!

Can you tell me which casinos have a microbrewery and if any serve the microbrew while you're gambling?
